People shared tips for acing his class, like telling him you love him.

"Professor Geller was dating this girl Elizabeth in my class and I'm pretty sure she got an A."

"Professor Geller was a nice guy, but had the weirdest outbursts. One day he asked us to change the desks around and kept screaming 'PIVOT!'. That was pretty weird, not to mention that he boosted up a kids grade because 'he was in love with him'. I loved him too, where was my grade?"

But the biggest complaint Professor Geller received was for his policy during semester breaks.

"He gave me 4 zero's for missing assignments I didn't show up for but WE WERE ON A BREAK."

"Everything was going great until I had some questions over spring break about our end of the year project. Then when I asked him about it when we got back, he went on this rant and kept yelling 'WE WERE ON A BREAK.'"
